Magnetic Force Microscope Effectively Scans Tiny Honeycomb Dipole Islands

Spin ice can be used to examine exotic properties of magnetic systems. Surprising observations have been made by physicists working with Prof. Dr. Hartmut Zabel at the Ruhr-Universität, using magnetic islands only micrometres in size that are placed on a periodic lattice with honeycomb symmetry.

UW Researchers Develop New Nanoparticle to Solve Medical Imaging Problem

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.

New Material Can Prove the Existence of Tiny Dipole Moment

Electrons are negatively charged elementary particles. They form the shells around atoms and ions. This or something similar is what you will find in text books. Soon, however, this information may have to be supplemented.

Researchers Make Magnetic Sheets Nanometers Thick

Materials do funny things at the nanoscale. A metal oxide complex called lanthanum strontium manganite is ferromagnetic in large quantities. But scaled to nanometer thickness, it becomes an insulator and loses much of its ferromagnetism. Same material, different behavior.
